iMPeovEMtnT .IN osent-'Anno .o1-Inans-` Specitioation forming part of Letters Patent No. i05,583, dated July 19, 1870.

T0 all whom it .may .Grimm- Be it k. own tha I, N. lil-WILSON, of Wil? sonburg, in the @Purity f .Harrison and State 0f Weetvrgiea have invented certain I'mmovements lili Oselletine Ghurns; and I do hrby deelarethat the following is a full, clear, and exact description thereof, reference being had to the annexed drawings, making part of this specification, in which?- Figure 1 is a side elevation of my improved oscillating churn, showing the mechanism for moving the dasher and the adjustable plati form upon which the barrel stands, together v arrangement of devices for adjusting the barrel thereof, and for securing the dasher-rod to the crank, and for holding the lid down upon the barrel, as will be more fully described hereinafter.

A in the drawings refers to the frame of the device, which may be of any desired form and of any suitable material, the only requirement being that it shall be adapted to receive the parts it is designed to support, one form being shown in the drawings. The sides of the frame rest upon orare secured to the base A1, and are secured at their upper ends by a cap, A2. 4 j Y B refers to an internal gear-wheel, which is to be fitted to revolve upon a stud which is secured to the frame A. To this wheel there is to be attached a crank for rotating it, as shown in Fig. 1 of the drawings.

B1 refers to a pinion, which may be of any 'required size, to give any desired number of revolutions to the crank-axle to one of the driving-wheels. This crank is to be secured to the outer end of crank-shaft U, which protrudes through the frame A a sufficient distance for that purpose.

C refers to the crank above alluded to, it having its bearingsin the sides A A of the frame, and being bent at its center, so as to -l'orm a crank of any desired length of throw, as shownin Fig. 1. y

Upon this shaft there may be placed a fly or balance wheel, B2, to give regularity to the movement thereof; or such wheel may bedispensedwith, and the machine will work well without it.4 A

D refers to a rod which is attached to the dasher, which-is within the barrel E. This rod passes up through the cover of the barrel, and is secured to the crank ot' shaft C by means of a clamp, D1, thumb-screw, D2, and block D3, the said block having an aperture through it for the passage of such crank.

It will be seen that, byloosening the thumbscrew, the dasher-rod may be adjusted within the block D3, so as to cause the dasher to assume any desired position within the barrel, which is shown at E, and may be of any desired capacity, and is to have, rising from its top, a frame-work, to serve as a guide for the dasher-rod. This frame-work consists oftwo springs, E1, and cross-bar E2, the springs being provided with hooks upon their upper ends, which hook `over the ends of the crossbar and recede into notches therein.

Upon the under side .of this cross-bar a springy piece'of metal, E3, curved as shown in Fig. 1, is secured, which, when the crossbar is placed over the hooked springs, bears with its scrolled ends upon the lid of the churn, and holds it firmly in place, at the'same time that it supports such cross-bar. This barrel is to be suspended upon screws D1 D1, which pass through the sides A A of the frame, and serve as pivots upon which said barrel oscillates, said barrel being provided with plates of metal upon its sides, which plates are to be provided with suitable recesses for the reception of the ends of the set-screws.

F refers to a platform, which, when in its lowest position, rests upon the base A1 of the frame. This platform is provided with uprights F1 F1, which rise from its ends, and serve as guides when the platform is being raised and lowered, there being cleats F F2 attached to the inside of the frame A A, to direct its movements.

EnIClilD G refers to a lever, which is to be attached to a shaft, G1, which has its bearings in the sides A A of the frame.

When the platform is in the position shown in Fig. 2, the lever G assumes a vertical position; but when it becomes necessary to raise the barrel, such lever is turned toward a horizontal position, which causes the shaft Gl to be partially rotated, by which means the arms Gr2 Gz come in contact with the under side of the platform, which causes the same to be raised, and with it the barrel of the churn, the set-screws D3 having been previously loosened.

As a consequence of the above-described arrangement of parts, the barrel and dasher may be adjusted so as to accommodate them to any quantity of material -which it may be desirable to churn at any one time. Thus, if it becomes necessary to churn the barrel nearly full, it may be so placed that the dasher will 'be lifted out of such material, so as to give the full amount of agitation caused by its entering the same; and the same result may be accomplished when only a small quantity of Y material is to be operated upon, without causing the same to be forced out ot" the barrel by the violence of the contact of the dasher therewith.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination 0f the crank-shaft U, dasher-rod D, block D3, clamp D1, and set screw D2, or their equivalents, their arrange ment being such that the dasher-rod may be confined to the cranksl at any desired point, substantially as and for the purpose speciied.

2. The combination and arrangemei t of the barrel E, platform F, and lever G, its shaft G1, and arms G2, or their equivalents, substantially as and for the purpose specified.

Y3. The combination of the hooked springs El, cross-bar E2, and curved spring E3, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
